ltq-deu: set correct control register for AES

Some devices initialize AES during boot and AES works out of the box
and the correct endianess is set.
NDC means (No Danube Compatibility Mode) and the endianess setting has
no effect if its set to 0.
NDC 0: OFF ENDI bit cannot be written as in Danube
To make it work for other devices, the NDC control register needs to
be set to 1.
